IMPROVEMENT IN MACHINERY FOR WORKING HIDES, SCOURING- LEATHER, 8m.

The Schedule referred to in ,these Letters Patent and making part nf thesame.

To all persons lo whom these presents may come:

VBe it known that 1', THERoN It. WVILLIAMs, of Salem, of thel county ofEssex and State of Massachusetts, have invented a new'and usefulImprove-l Figure 2, a slde elevation ot' a pair of tool-holders, with myimproved arrangement ot' thesliekers or tools thereof.

1n leather-scouring machines, as heretofore constructed, the slickers,orsconring-stones, or tools, have generally been arranged at rightangles with the direction of their traverse. When set in this mannerthey, while in operation, stretch or` expand the leather.

only in one direction, the Shanks and bellies being liable, under suchexpansion, to become wrinkled or plaited in folds.- In passing over theshank the tools are also liable to catch and throw up th'e leather.

Lith my invention these difficulties areV ohviated, suchinventionconsisting in a new arrangement of the scouring-stone, that is, so as tohe oblique to the line Vof traverse, one stone of the pair being-at thesame time disposed at an angle with the other. In this way theirrubbing-edges, instead 0f being at right angles to the direction ofmovement of them, stand 0bliquely therewith, and cause the leather to bespread out laterally as well as longitudinally, the same servin g toprevent the formation of wrinkles or plaits, as well as to remove anywhich may exist in the leather.

The two stones, arranged `at an' angle with each other, and obliqnely totheir paths of motion, spread the leather in opposite directions awayfrom the medial line of their general traverse, and thereby greatlyfacilitate or improve the process of setting-out and scouring theleather.

Furthermore, when the stones ofI a pair are arranged at an angle witheach other, as represented in the accompanying drawing, there will helittle or no liability of their catching int-o or throwing up leather,while they may be at work upon it.

In thedrawingy A B denote a pair of the tool-carriers, arranged, on acommon shaft, O, and provided with tools or seour ersl) D, disposed inmanner 'as hereinhefore mentioned.

` lVha-t I claim as my invention 4or improvement in. machines forscouring or setting-out leather or hides The new arrangement ot' eachtool in its carrier, viz., so that such tool while in ,operation shallstand lohliquely to its traverse or path ot' movement.

Also, the tools oi'each pair as arranged at an angle with each other,and ohliquely relatively to the direction of their traverse, ashereinbefore described.
